About this Training Course There are various kinds of geophysical data available. They are separated into seismic and non-seismic (multi-physics) data. Non-seismic or multi-physics data (which includes gravity, magnetics, electrical, electromagnetics, spectral etc - apart from providing complimentary information to seismic) is the main source of information for very shallow subsurface applications such as engineering, mapping pollution, archaeology, geothermal energy, and related areas. This 5 full-day blended course will focus specifically on seismic data which is the main method used in the Oil & Gas industry. In this blended course, participants will be equipped to understand that seismic data represents the movement of the surface, resulting from waves generated by a source, dynamite or vibrator which are reflected by changes in the subsurface rocks. The basic principles of acquisition and processing will be explained and insights into advanced methods, allowing a much more accurate interpretation of seismic data than previously considered possible, will also be provided. This blended course contains an introduction to Machine Learning and its important role in all aspects of seismic acquisition, processing, and interpretation. There is no need to know in detail how the algorithms work internally but it is necessary to know how to use them correctly to achieve optimum results. Training Objectives By attending this course, participants will be able to acquire the following: Obtain an understanding of the strengths and limitations of geophysical methods, specifically seismic, and the costs and risks involved, and how to reduce these. Be able to communicate more effectively with staff in other disciplines. Understand the potential applications of seismic data and know how to formulate the requirements needed for prospect and field evaluation. Gain an awareness of modern seismic technology. Apply the learning in a series of practical, illustrative exercises. Know what types of questions to ask to assess the necessary quality of a seismic project in its role in a sequence of E&P activities Target Audience The blended course is intended for non-geophysicists who have intensive interaction with geophysicists. But it may be of interest to those who want to know about the recent progress made in geophysics, leading to amazing imaging results, which could not be imagined a decade ago. The blended course will bring to the attention of the geologists, petrophysicists and reservoir/petroleum engineers an awareness of how the data they will work with is acquired and processed by the geophysicist. It will introduce the concepts that are of importance in geophysics and thus relevant for non-geophysicists to know and be able to communicate with geophysicists as well as formulate their requests. Course Level Intermediate Trainer Your expert course leader has degree in Geology (University of Leiden), a Master's degree in Theoretical Geophysics (University of Utrecht) and a PhD in Utrecht on 'Full wave theory and the structure of the lower mantle'. This involved forward modelling of P- and S-waves diffracted around the core-mantle boundary and comparison of the frequency-dependent attenuation of the signal with those obtained from major earthquakes observed at long offsets in the 'shadow zone' of the core. These observations were then translated into rock properties of the D' transition zone. After his PhD, he joined Shell Research in The Netherlands to develop methods to predict lithology and pore-fluid based on seismic, petrophysical and geological data. He subsequently worked for Shell in London to interpret seismic data from the Central North Sea Graben. As part of the Quantitative Interpretation assignment, he was also actively involved in managing, processing and interpreting Offshore Seismic Profiling experiments. After his return to The Netherlands, he headed a team for the development of 3D interpretation methods using multi-attribute statistical and pattern recognition analysis on workstations. After a period of Quality Assurance of 'Contractor' software for seismic processing, he became responsible for Geophysics in the Shell Learning Centre. During that period, he was also a part-time professor in Applied Geophysics at the University of Utrecht. From 2001 to 2005, he worked on the development of Potential Field Methods (Gravity, Magnetics) for detecting oil and gas. Finally, he became a champion on the use of EM methods and became involved in designing acquisition, processing and interpretation methods for Marine Controlled Source EM (CSEM) methods. After his retirement from Shell, he founded his own company, specialising in courses on acquisition, processing and interpretation of geophysical data (seismic, gravity, magnetic and electromagnetic data), providing courses to International and National energy companies. In the last couple of years, he became keenly interested in the use of Machine Learning in Geophysics. Apart from incorporating 'Artificial Intelligence' in his courses, he also developed a dedicated Machine Learning course for geophysics.

About this Virtual Instructor Led Training (VILT) This 5 half-day Virtual Instructor Led Training (VILT) course covers carbon capture and geological storage of carbon dioxide. Burning fossil fuels for energy is a major source of carbon dioxide emissions to the atmosphere. Most anthropogenic (man-made) carbon dioxide is emitted by coal-fired or gas-fired power plants, and significant quantities of carbon dioxide are emitted through the production and separation of carbon dioxide-rich natural gas and industries such as cement, iron and steel. Carbon Capture Utilization and Storage, or CCUS, involves the long-term storage of captured carbon dioxide emissions in subsurface geologic formations. This VILT course covers all aspects of CCUS including transport, storage and monitoring, economics and community engagement. It explores in detail the challenges of the current technology of geological storage, monitoring and verification including examples from working projects around the world. Many of these technologies are commonly employed by the petroleum industry. Successful deployment of CCUS will also require economic incentives, appropriate regulation, clarity on liability issues and acceptance by the community. These aspects of CCUS, and the corresponding opportunities for appropriately skilled organisations and individuals also will be discussed. Course Content at a Glance Context for CCS/CCUS as An Emissions-reduction Measure Principles of Geological Storage Finding Geological Storage Sites Stationary Sources of Carbon Dioxide for Capture Carbon Dioxide Capture Technologies Compression and Transport of Carbon Dioxide Economics of CCS/CCUS Community, Safety, Legal & Regulatory Issues Risk Assessment Training Objectives Upon completion of this VILT course, participants will be able to: Identify the need for Carbon Capture and Storage (CCS) Outline the key steps in the Carbon Capture and Storage process Distinguish between reservoir rocks and sealing rocks Describe the importance of permeability and porosity to storing carbon dioxide Contrast the geological structures and trapping mechanisms for storing carbon dioxide Describe the changes in geologically stored carbon dioxide over time Outline the monitoring techniques employed to ensure the carbon dioxide is safely stored Appreciate the industrial applications of carbon dioxide capture Recognize the scale of industry required for transporting and storing carbon dioxide Describe economic considerations for CCS/CCUS Outline the economic and environmental opportunities and challenges with using carbon dioxide injection in a range of applications Explain the challenges of regulatory frameworks and public acceptance in a CCS/CCUS project Identify potential risks of a CCS/CCUS project Outline the risk assessment and management process Target Audience This VILT course is ideally suited for a technical audience - geoscientists, petroleum and chemical engineers - as well as for economists, regulators, legal staff and managers wishing to learn more about the details of both the technical, regulatory and socio-economic aspects of carbon capture and storage.
